MACHINE FOR BORING PUMP-LOGS, 86C.

SPECIFICATION forming part of Letters Patent No. 266,643, dated October 31, 1882.

Application filed January 3l, 1882. (No model.) Patented in Canada: November 29, 1850, No. 19,051.

To all whom it may concern:

Be it known that I, PARDON T. PERKINS, of Oswego, in the county ot' Oswego, in the State the following, taken in connection with the accompanying drawings, is a full, clear, and cxact description. (For this improvement I have received Letters Patent in Canada, No. 12,051, dated November 29, 1880.)

This invention consists, tirst, in a novel construction of the head-block ot' themachine, whereby the same is adapted to receive and hold angers ot'ditterent makes and sizes-as, for example,the \Vyckol'i" auger and the core7 auger.

lt also relates to an automatic feeding apparatus, by means ot' which the log operated on may be fed against the cutter or back therefrom at varying speed, automatic stops being arranged so as to stop the movement ot' the log-carriage in either direction.

The invention also consists iu other matters ot' detail, all as hereinafter t'ully described, and more specifically set forth in the claims.

In the annexed drawings, Figure lis a side elevation ot' the machine, showing the relative position f some ot' the more important parts. Fig. 2 is an end view ot' the same on an enlarged scale. Fig. 3 shows a larger journalbox inserted in the head-block to receive an auger ot larger diameter. Figs. 4 and 5 show detached views of a portion of the head-block with different sizes otl journal-boxes inserted therein. Fig. 6 shows the end or'l a log at'ter having been eut into by a core-auger. Fig. 7 is a front side elevation oi' the head-block, similar to the view in Fig. 1, showing the same adapted for holding and operating a- Wyckoit' auger, which is shown in place, the most ot' said parts being shown in longitudinal section. Fig. 8 shows a side elevation of a part ofthe reverse side ofthe trame or bed, bringing into view the feeding apparatus attached tosaid reverse side ot' the machine. Fig. 9 is a plan of a part ot' the frame or bed, and Fig. 10 shows an elevation taken at the left-hand end of Fig. 9.

Similar letters of reference indicate corresponding parts in all the gures.

The letter A represents the frame or bed for supporting' the other parts, made in suitable proportions. y

B denotes the head-block for carrying the various angers, bolted to one end ofthe trame, and consisting, principally, of two parallel arched risers, O C. rlhe risers or arches are expanded at the top by downwardly-curved parts l), which open upward, said openings being sufficiently large to receive the largest-sized journal-boxes desired for use, as shown in the detail view at Fig. 5. Smaller-sized journalboXes are made to tit the same openings, as shown at Fig. 4.

el, Figs. 1 and 2, is a tube or pipe turned true on its exterior surface, resting in journal-boxes in the head-block, and havinga driving-pulley, D, secured to it. Upon its exterior is placed Spirally a ribbon ot' metal, which serves to draw the chips out ofthe cut, thus preventing clogging. At the end ot' the tube dis secured a suitable cutter,]", which cuts an annular opening through the log, as shown in Fig. 6, leaving a solid core, k, which passes within the tube l as the log advances against the cutter. rlhe extreme end ot' the tube rests within a center rest or guide, E.

The log F rests within log rests or jaws G, formed in pairs opposing each other, the jaws otl each paix' being moved toward or from each other by means ot hand-wheels L and right and left screws g, running transversely across the frame A. 'll1ejawslides IL rest upon plates a, which are grooved at their ends and fitted to slide Ialong the edges ot the guiderails l, which are secured to the upper surface of the fralneA, as shown in Figs. 9 and 10. said guiderails` l being so secured to the frame as to slightly overlap the same on the inner side thereof. Thejaw-slides h are attached to the respective plates a, which latter are secured to a plank, K, Fig. 1t), and said plank, plates, and jaws, with their attachments, together constituting a log-carriage adapted to slide longitudinally along the rails Zon the frame A. The carriage is moved along the frame by means of a rack and pinion, I and N, beneath the plank, the pinion being keyed to a shalt, m, running through the frame from side to side, having a bevel-gear, u, at one end, and squared at the IOO other end to receive a crank or wrench by means of which the carriage can be moved by hand.

Fig. 8 shows the feeding mechanism on the rear side of the frame. The bevel-gear n is engaged by opposing pinionspp, revolving loosely on a shaft, t,journaled in bearings y. A sliding clutch, b', is secured to the shaft by a spline in the usual manner, and may be operated to engage either pinion, as desired. c' and d' are respectively a gear and pinion revolving loosely upon the shaft t, and a' is aclutch similar to b', which may be moved to engage either gear or pinion, as desired. A shaft, 0, journaled in boxes I), beneath the shaft t, has keyed to it the gears R and S- and the pinion T. A pulley-shaft, V, has a pinion, r, which drives the gear It, and by means of a belt on the pulley Y the feed mechanism is operated. The gear and 'pinion S and T drive respectively the .pinion and gear d' and c'. The clutch b' is operated by a shifter, f', Figs. Sand 10, which extends across under the frame, with a handle, fw, in convenient reach of the operator. The clutch a is operated in the same manner by a shifter, c, and handle u. If the clutch a is made toengage the gear c', the log-carriage will be moved toward or from the head-block, acg

cording as the clutch b' is brought into engagement with the pinion p or p'. After the log has been bored through it is desirable to move the carriage back more rapidly than it was fed forward. This is accomplished by throwing the clutch a' over so as to engage. the pinion d', when the shaft t will be more rapidly rotated. An arm, g', Figs. 1 and l0, reaching up from the shifter-f' within theframe, is moved by adjustable dogs e', secured to some part of the carriage. These dogs may be so adjusted as to move the shifter and throw the clutch b out of either bevel-pinion and stop the motion of the carriage at any time, so that the carriage shall not be driven against the head-block in moving in one direction or too far in the other direction.

1n using the Wyckoff auger it'is necessary to have four bea-rings at the head-block. To effect this I attach two brackets, A' and D', Fig. 7, to the rear riser, G. The tube cof the said auger rests in the bearing of the riser U' and the bearing ofthe bracket D', with a drivingpulley, B', between them. The riser C' and bracket A' hold a spindle, t, which, by means of a socket and set-screw at o, drives the chipextractor x, which consists of a rod, with a dan ge wound spirally around it, rotating within the tube e. The chip-extractor is driven more rapidly than the tube e,'and in an opposite direction by a pulley, F', and belt thereon, the chips being-drawn out of the tube and dropped at the rear end thereof by the extractor, as indicated by the arrow e'. The center rest, E, for the angers is com posed of a base-piece or arch, G', and ajournal-box, I', bolted thereon.

For different-sized angers I have differentsized journal-boxes I', all fitted to the basepiece G'.

Having thus fully described my invention, what I claim as new, and desire' to secure by Letters Patent, is Y 1. In a wood-pipe-boring machine, the combination of the frame A, stationary head-block B, tube d, provided with a spiral ribbon and a cutter, f, at its outer extremity, with a log-carriage operated by a rack and pinion, the pinion-shaft being provided at one of its extremities with a bevel-gear, n, adapted to engage opposing pinions, p p', having a clutch, b', constructed and arranged as shown, whereby the feed may be automatically tripped or stopped by the motion of the log-carriage, substan-v tially as described.

2. In combination with the frame A, provided with an adjustable head-block, B, and a suitable boring-tool, the log-carriage provided with a feeding device consisting of the shaft t, having thereon the gears r d' c', bevel-gears p p', and clutches a b', respectively, between said sets of plain and beveled gears, and the shaft O, provided with the engaging gears R S T, the said feeding device being adapted-,with suitable shifters, to engage the bevel-gearnon the pinion-shaft of the logcarriage, whereby the feed may be automatically tripped or stopped, all substantially as described.

3. A wood-pipe-boring machine having a head-block, B, provided with removable journal-brackets A' and D', for the purpose of ac' commodating either a Vyckoff or core auger, substantially as described and shown.

In testimony WhereofI have hereunto signed my name and affixed my seal, in the presence of two attesting witnesses, at Syracuse, in the county of Onondaga, in the State of New York, this 23d day of January, 1882.
